zBrush Model & Map for Displacement Render tests

YAAAAAAAAAA! Lynx you’re a frickn genius!!

If you were here I would kiss you on the lips… :slight_smile:

Now of course I’m extremely ticked that Newtek never bothered to fix this problem 2 years ago. Does it work ok on a render farm? I haven’t tried that yet.

Any chance you have a max plugin that will do the same thing :slight_smile:

<BLOCKQUOTE>quote:</font><HR>had problems if I set my subdivison to anything but first. . .usually I use last or after bones.<HR></BLOCKQUOTE>

Try to set the evaluation of NormalDisplacement to “World Coordinates”, and SubD to “After Bones”. Morph Mixer should still get applied before bones, then SubD, then ND…i hope :slight_smile:

RobW, the tif tip is on this thread, man. When I tried that, it didn’t work at all… Not much of a problem though, since it’s easy enough to use HDRshop. :+1:

RobW: Cheers, I’ll try that although I’ll be shocked if that works - too easy.

Grub: I’m still getting problems with HDRShop converting the TIFF into an HDR - just gives me nasty banding in LW. Hopefully the TIFF loader for LW will get fixed soon, or ZBrush expands it’s range of savers.

Mattoo- I’m getting some banding also, I think I’m going to look into using Cinepaint. :+1:

Grub- yeah, and only two pages back :slight_smile: I should have just read the thread again. Thanks for that tip Tmac. Now with Lynx’s excellent plugin, things are much quicker- save from zbrush, rename extension, load, set midpoint to 50. Done.

LW does load the .tiff no problem. It is listed as 32 bit in LW, which I imagine is just the file format and not the actual bit depth. Not sure why it would work here and not there Grub. Using LW 7.5c here.

I’m not getting any luck with the renaming to ‘.tiff’ either. And I’ve tried in both LW7.5a and LW8.

What program did you use to flip the texture vertically RobW?
I’ve tried renaming the original .tif and that refuses to load aswell - so maybe it’s the program that you used to flip it that allows your LW to read it…?

Grub; I tried Cinepaint and I couldn’t get that to spit out anything useful. I thought it handled .hdr’s…?
I only found a Cineon saver which LW refused to load the image anyway.

Maybe there’s some third party loaders/savers for CinePaint?

Weird, i was pretty sure i got to load the 16bit tif as .tiff but i must’ve confused the files because it does not work anymore :smiley:

Anyway, i wrote a 16bit grayscale tiff loader that converts them to 32bit float grayscale (LW only supports 8bit integer per sample or 32bit float)
http://lynx.aspect-design.de/plugins/tiff16bps.htm

To me it seems like the HDRs don’t really save all the precision, sure they can reproduce much more than 256 brightness levels, but, we want them to have between 0% and 100%, and HDR is more about supporting values much greater than 100%…

-edit-
what i really find disappointing is that Photoshop can’t even flip 16bps images…what bad joke is that?

Mattoo- actually I’m just flipping it in Zbrush before export. Flip, export (no splitting into neg and pos anymore), go to load in layout, rename extension right in the file-requester, hit load. Just tested it again to be sure I wasn’t imagining things.
As you see I’m not doing anything strange to get it to load. I’m as suprised as anyone it works, but won’t complain.

[edit]

Just looked in the input-output plugin directory. There is a tiff.p loader- perhaps it had to be installed manually? Dunno.

Once again Lynx3D is here to save the day! :slight_smile:

Works like a dream, fantastic stuff!

No banding what so ever, genius.

RobW: I tried your method - still got the same negative result. I even looked on Flay for other third party TIFF loaders, there’s one from DStorm but it’s ancient, LW 5.6 days, I’d doubt it would work.
You’ve got some serious mojo there, I wouldn’t mess with it - it seems to work for you.

Mattoo- Cinepaint was no good either, I also tried a prog called hdrview, which actually loads the tifs but they turn out horrid. As for 16 bit tifs, what a pain in the butt. :smiley:

RobW- I installed those plugs, but alas no luck. I can load 8bit tifs ok but not 16bit. I’m wondering if you’re using a Mac version, the tif loader might be different.

Lynx3d- Wow, another plug to hopefully save the day, gotta test that out, cheers!

This one is displaced in Lightwave.

The first and third images are after Lynx’s Normal Displacement is applied. Some (for me) strange seams appear and ruin the model.

Second and fourth are with bump maps.

The displacement worked fine in zb. Anyone know what I’m doing wrong here?

This was made with Max5 and Vray. Sorry for using the all-to-well-know-kitchenprobe.hdr. :wink:

Took about 11:00 min.

Hi Sami Sorjonen,

Super nice work!!!

Animation:Master
8Bit deep .bmp (vert. flip)

@basselito: do you change something at the displacementmap? Maybe make smoother? Can I use your pic to show the directly rendering difference from my Piy, to your? I want upload it in the Animation:Master-Forum.

I wonder about the nice and simple import to A:M

@Sami Sorjonen :
Do you model complete head in ZBrush?
Edgeloops, too?
Or you have modified it in another 3D-Programm?

JackMcRip:

“Do you model complete head in ZBrush?
Edgeloops, too?”

  • Make it lowres again by genarating lower subdividision level. I remember it can be done…
  • Then you see the mesh structure - I think i made few minor poly changes in Silo, to the back of head and neck, but it was originally built in Z-brush, with Zspheres
  • Everything else is done in Zbrush, using zsphere style “bubble head” as starting point :slight_smile:

basselito:

  • Really good quality displacement render! - Seems like Vray is currently the best option for rendering displacement mapped objects :slight_smile:

-S-S

@Sami Sorjonen : what is the mapping-typ you use at this head???
I try to make a model in ZBrush and i need for A:M the same mapping-typ.
